Conclusion The insider trading debate traditionally discusses the pros and cons of insider trading and draws a conclusion about the desirability
or undesirability of public regulation of insider trading. One of the most important arguments against insider trading is
that it generates agency problems that shareholders cannot resolve and that, therefore, insider trading should be publicly
regulated. We have challenged this argument for failing to engage in comparative institutional analysis. We argued that when
the negative aspects of insider trading, namely, the agency problems that it may create, are considered, it is necessary to
engage in comparative institutional analysis and how these problems can be resolved under two different economic systems:
the market economy and interventionism.
We have been led to the conclusion that under a market economy, shareholders do have mechanisms to protect themselves against
agency problems generated by insider trading and that these problems are reduced to a minimum. We have shown that interventionism
hampers the functioning and reduces the disciplinary role of such mechanisms. Therefore, insiders have indeed more latitude
to engage in these discretionary behaviors, pointed out by the supporters of the insider-trading-as-an-agency-problem argument,
that harm shareholders. Finally, we have shown that the failures of government regulation reinforce this tendency of insiders’
behavior.
We conclude that we cannot justify a public regulation of insider trading based on the insider-trading-as-agency-problem argument. 相似文献

The objective of this research was to estimate logistic expenditure for the global economy. An Artificial Neural Network was used to generate national estimates. The estimation set constitutes 24 countries representing approximately 75% of the global Gross Domestic Product. The model utilizes variables that capture economic activity, transportation activity, income level, country size, and geographic location. This research updates previous estimates and represents continuous improvement of the estimation method, including new input variables, better information quality, mathematical model refinement, and methods of model validation. 相似文献

Digital services are increasingly important in the economy and in society in general, as they continue to shift from being a specific sector of activities to becoming the basis for the provision of most services. They offer multiple new opportunities from which consumers benefit daily, but they also raise novel questions for consumer protection. 相似文献

We investigate the dynamics of the value anomaly in order to identify the driving forces of the anomaly. We show that the large positive value-minus-growth portfolio returns are explained by an over-reaction (under-reaction) to the positive (negative) market movements in short, specific time periods, during which the average returns of value-minus-growth portfolios are more than 2% a month. We propose an explanation based on behavioral biases: the dynamics of the value anomaly reflect the increased speed of return reversals subsequent to overreaction. Two conditions that increase the return reversals are proposed: when investors respond to public signals asymmetrically or when public signals become noisy. Our empirical results reveal that the value anomaly is explained by either one of these two channels. 相似文献

We develop a model of innovation and learning that incorporates explicitly the need for a firm to conduct its own research and development (R&D) in order to realize involuntary spillovers from other firms’ R&D activity and the development of absorptive capacity of research firms over time. The conclusions of the model follow directly from the functional forms that are used to describe the generation and absorption of technological knowledge. The first proposition formally characterizes the steady-state rate of growth of technology for the model. The analysis also shows how some of the key features of two distinct, pure modes of organization of the production of new knowledge, the R&D model and the new localized knowledge model, are implied by our model by simply drastically changing the relative magnitude of two exogenous parameters: the ease of learning and the pace of knowledge advance. The second proposition formally characterizes the connections implied by the model between involuntary spillovers and absorptive capacity. Analysis of the long-term interactions between involuntary spillovers of knowledge and absorptive capacity provides the essential insights into an understanding of the elements of a self-sustained process of endogenous growth. The third and last formal proposition of this paper accommodates firm-level arguments and the crucial role of a firm's absorptive capacity in taking advantage of its location in clusters, as implied by the theoretical model. 相似文献

The paper develops a formal model of external knowledge and identifies the role of knowledge multipliers. Social interactions and knowledge multipliers play a crucial role in determining the rate of technological change. The analytical identification of the knowledge multiplier expression constitutes a key step in the appreciation of the crucial role of knowledge interactions. First, social considerations endogenously change the knowledge production function of each firm. The knowledge multiplier is the specific mechanism by means of which external knowledge contributes to enhance the innovative capacity of each firm. The production function of knowledge shows that the larger the knowledge multiplier is the stronger are the cumulative positive effects of external knowledge on the generation of new knowledge. Second, social considerations explain the long-run dynamics of innovation. Social reinforcement and the knowledge multiplier determine the rise or fall in the rate of accumulation of technological knowledge. 相似文献

In response to competitive pressures created by privatization, telecom firms in developing countries are establishing alliances and other types of linkages—mergers and acquisitions—with foreign partners to ensure customer competitive advantages in global markets. However, there have been very few studies on the alliances of telecom operators in Brazil, an increasingly important BRIC. This article presents the results of research that aimed to fill this gap by identifying, from a network/international perspective, the opportunities/threats created by the relevant linkages of leading telecom operators in Brazil. The results suggest that acquisitions—and especially alliance-type linkages with foreign partners—have created opportunities for boosting performance, in keeping with their new strategic profile. 相似文献

Based on an original data set of more than 500,000 non-alcoholic beverage price records, we evaluate the impact on consumer prices of the ‘soda tax’, an excise on drinks with added sugar or sweetener, introduced in France in January 2012. We adopt a difference in differences approach and find that the tax was gradually passed through to the prices of the taxed beverages. After 6 months of its introduction, it was fully shifted to soda prices and almost fully shifted to the prices of fruit drinks, while the pass-through for flavoured waters was incomplete. We also find that the pass-through was heterogeneous across brands and retail groups. 相似文献

Developing countries pay substantially higher transportation costs than developed nations, which leads to less trade and perhaps lower incomes. This paper investigates price discrimination in the shipping industry and the role it plays in determining transportation costs. In the presence of market power, shipping prices depend on the demand characteristics of goods being traded. We show theoretically and estimate empirically that ocean cargo carriers charge higher prices when transporting goods with higher product prices, lower import demand elasticities, and higher tariffs, and when facing fewer competitors on a trade route. These characteristics explain more variation in shipping prices than do conventional proxies such as distance, and significantly contribute to the higher shipping prices facing the developing world. A simple back of the envelope calculation suggests that eliminating market power in shipping would boost trade volumes by 5.9% (for the US) to 15.2% (for Latin America). Our findings are also important for evaluating the impact of tariff liberalization. Cargo carriers decrease shipping prices by 1–2% for every 1% reduction in tariffs. 相似文献
